At Illinois Pulley & Gear, our flanging process is unique. Each of our flanging methods promise the highest quality product. We know that pulley motion cannot stop – inopportune pulley failure can cause significant damage to machinery.

Roll Staking

Roll staking is an excellent way of attaching flanges to smaller timing pulleys. Roll staking produces a crimp 100% of the way around the edge of the flange, rather than on 6 to 8 points. This method is superior to conventional staking methods that only hold a small percentage of the flange to the pulley.

Heat Shrinking

Heat shrinking is an exceptional way of attaching heavy, large-diameter flanges to timing pulleys. The flanges are heated to 450 degrees Fahrenheit or more and then placed onto the pulleys’ flange step, which is 0.015” to 0.020” larger in diameter than the ID of the flange in its cold state. Upon cooling, the flange shrinks onto the flange step of the pulley, permanently holding it in place.

Bolt-On Flanges

flanging process

For the ultimate option, IPG makes bolt-on flanges – the heaviest and most durable flanges available. Flanges are held to the sides of the timing pulleys by flat head screws. An additional advantage to bolt-on flanges is the ability to remove the flange for belt maintenance. Other flanging methods do not allow flange removal for maintenance purposes.
